DOOR FASTENER.

Application led August 2, 1923. Serial No. 655,218.

This invention relates to door fasteners and especially to improvements on the structure shown in my former Patent entitled Door lock, No. 1,456,041, issued May 22, 1923.

The object of the present invention4 is to provide a fastener which is particularly adapted for installation on French doors and the like; lto generally improve and simplify the construction and operation of locks of the character described; to provide a fastener which requires a minimum of cutting, fitting and removal of wood when installe and which will fit practically anystandard door even though the thickness of the same may vary considerably; to provide a fastener which is secured from one side ofgthe door onl by an intermediate plate and screws w ich engage the fastener housing, and further to provide means whereby the securing screws and intermediate plate are entirely concealed when thev fastener is in place. Other objects will hereinafter ap ear. f

ne form which my invention may assume is exemplified inthe following description and illustrated in the accompanying drawings, in which- 4Fig. 1 is a horizontal section of the fastener showing'it in position in the door. Fig. 2 is a section on line 2-'2, Fig. 1.

Referring to the drawings in detail, A indicates a fastener housing of unit construction. This housing is cylindrical in cross section and elongated as shown. One end of the housing is closed by an integral end plate 2, and the opposite end by an escutcheon plate 3. .The end plate 2 is extended to form a bearing 4, and the escutcheon late 3 is similarly extended to form a bearing 5. Extending through the bearings 4 and 5 is a knob supporting spindle which is divided into two sections as indicated at 6 and 7; these spindles forming supports for knobs 8 and 9 as shown. The ends of the spindles are square to receive the knobs and to secure the same against turning movement with relation to the spindle sections, and they may be secured by screws or the like as indicated at 10. Formed on the inner end of each spindle section is a circular plate 11 and connecting said plates and the spindle sections 6 and 7 are a plurality 'of cross-bars as indicated atv 12, 13 and 14.

The plates 11, together with the connect-ing bars 12, 13 and 14, will hereinafter be referr-ed to as the spindle barrel, the barrel being provided for the purpose of retracting a latch 15.

The open end of the cylindrical fastener houslng is provided with an annular flange 16. This flange is circular in formation 'and is beveled to permit the escutcheon plate 3 to be snapped on and secured when the fastener is in position in the door. One side of the fastener housing is cut away as indicated at 17 and an opening is thus formed for the reception of the latch housing generally indicated at 18, the latch housing being secured to the fastener housing in any suitable manner or as here indicated by means of rivets 19. One side of the fiange. 16 is extended to form a cover plate 20 for the latch housing and a rectangular chamber is thus formed which serves as a guide for the latch 15 and the mechanism whereby it is actuated. This mechanism Consists of 'a pair of inwardly extending arms 21 and 22. These arms are bent at their inner end to form hook like projections 23 and they are so positioned as to be engaged by the cross-bars 13 and 14. The latch is normally held in a projected position by' means of a helical spring 24, this spring being positioned between the arms 21 and 22 and being interposed between the latch 15 and a cross-bar 25.v

When it is desired to retract the latch 15 it is only necessary to turn the spindle barrel by means of either knob. This turning movement causes either the cross-bar 13 or the cross-bar 14 to engage the hook like projections 23. Inward movement is thus imparted to the arms 21 and 22 and to the latch 15, and when the knob is released normal position is again assumed as spring 24 is placed under tension when the knobs and spindle barrel are manually turned and thus exert suiiicient, pressure to return the same to normal position when the knobs are released. f The fastener proper when applied to a door is installed in the following manner: A hole is first drilled through the door with an auger or suitable tool, the hole being of a diameter which will permit the cylindrie cal casing A to fit snugly therein. The inner face of the door is then channeled to receive the latch housing and the ent-ire operation of cutting the door to install the fastener is, thus completed. The fastener is vnext applied by inserting the cylindrical housing and forcing it inwardly until the fiange 16 engages the face of the door. The escutcheon plate may then be applied, and an intermediate plate, such as shown at 27, is next applied, this plate being slidably mounted on the bearing extension 4 of the fastener housing. A pair of screws 2S is then passed through the intermediate plate and as the inner ends of the screws have a threaded engagement with the fastener' housing at the points indicated at 29, it is obvious that the plate 27 will be pulled taut against the opposite face of the door, While the fiange 16 and the eseutcheon plate 3 will be pulled snugly against the opposite face of the door. The fastener is in this manner secured to the door and the escutcheon plate 30 is then applied and snapped over the intermediate plate 27. The knob 8 is placed in position and secured by the screw 10 and the whole operation of installing the fastener is completed. No screws are required on the end which is covered by the escutcheon plate 3, and as the screws 28 are hidden by the escutcheon plate 30, it can be seen that the entire fastening mechanism is concealed and the appearance of the fastener is accordingly simplified and improved. The fastener is at the same time rigidly secured and cannot be tampered with as the escutcheon plate 30, the intermediate plate 7, and the screws 28, are preferably positioned on the inside of the door.

By referring to Fig. l, it will be noted that the fastener housing A is slightly shorter than the thickness of the door. This is an important feature as it permits the fastener to be fitted to doors of various thicknesses; that is, the length of the fastener housing A is such that it will take care of a door of minimum thickness, but

. as the bearing extension' 4leXtends a considerable distance and as the plates 27 and 30 are slidably mounted thereon, doors having greater thickness can readily be taken care of.

YWhile certain features of the present invention are more or less specifically illustrated, l wish it understood that various changes in form and proportion may bc resorted. to within the scope of the appended claims; similarly, that the materials and finish of the several parts employed may be .such the experience and judgment. ofr the manufacturer may dictate or various uses may demand.
